IMPROVEMENT IN WATER-CLOSET APPARATUS.

Specification forming part of Letters Patent No. 157,211, dated November24, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, ARGHIBALD MoGIL- CHRIST, of New York city, in thecounty and State of New York, have invented a new and useful Improvementin Water-Closet Apparatus, of which the following is a specification:

The figure is a vertical section of my improved apparatus.

My invention has for its object to furnish an improved water-closetapparatus, which shall be so constructed as to render the use of a trapunnecessary, and at the same time will prevent any unpleasant odor fromescaping through the pipe; which will shut off the water automaticallyand guard against an overflow while allowing a sutficient amount ofwater to flow in after the valve has been closed; and which shall besimple in construction andnot liable to get out of order.

The invention consists in the combination of the two chambers and theirconnectingtube, the inner tube, the smaller lower valve, the largerupper valve, the small valve, the red, the lever, and the float, withthe water pipe, the case, and the basin; and in the combination of theball-valve, the tube and rod, the branch tube and its valve, with thecase and the basin, as hereinafter fully described.

A represents a case in which the operating mechanism is placed. Thelower end of the case A is connected with the upper end of thedischargepipe B, and its lower part is provided with a branch pipe, G,with which the basin D is connected. E is the pipe through which thewater enters the apparatus, and

with the end of which is connected a small chamber, F. From the chamberF a tube, Gr, leads to a similar chamber, H. The chambers F H are madewater-tight, and with their connecting-tube G is connected the end ofthe pipe I, through which the water flows into the basin D. Through thetube G is passed a tube, J, which is made smaller and a little longerthan the tube G, and has a valve attached to each end, the lower valve,K, within the chamber F being made smaller than the upper valve, L,within the upper chamber H.

The lower end of the inner tube J is closed by a small valve, M. whichis attached to the lo er end of a rod, N. The rod N passes up throughthe tube J, through the top wall of the upper chamber H, and its upperend is pivoted to a lever, O, the end of which is pivoted to a studattached to the top of the chamber H, or to some other convenientsupport. To the other or free end of the lever O is attached asemicircular block or case, I, which is made light enough to float uponthe water and heavy enough to press down and open the valve M againstthe pressure of the water in the chamber F, into which the inlet-pipe Eopens. The lower end of the case A is closed by a ball-valve, Q, made ofrubber or other suitable material, and which is secured to the lower endof a small tube, R, by nuts, as shown in the figure. The tube It passesup through the case A and through a hole in the lever O, and to itsupper end, above the said lever O, is attached the rod S, by which theball Q is raised to allow the contents of the basin 1) and case A toflow out.

With the upper end of the tube R is connected a branch tube, T, withinwhich is placed a ball-valve, U, as shown in the figure, and which isarranged a little above the ordinary water-line, so that, should thewater rise above the ordinary level it will raise the valve U and flowoff through the tube R, thus guarding against overflow, while the valveU will prevent any unpleasant odor from escaping through the said tubeR.

With this construction, when the ball Q is raised, by means of the tubeR and rod S, the contents of the basin D and case A will flow offthrough the pipe B. As the water lowers in the case-A the float P sinks,which presses down the rod N and opens the small valve M, allowing thewater to flow through the tube J into the upper chamber H. The valve Lbeing larger than the valve K, the press ure of the water forces downthe valve L and tubes J, opening the valve K, which allows the water toflow through the tube G into the pipe I, and through it into the basinD.

When the ball Q is lowered into place the water rises in the case A andraises the float P. This closes the valve M and shuts off thewater-pressure from the upper valve L, which allows the water to slowlyclose the valve K as the water escapes from the chamber H, the valve Lbeing made to fit loosely, so that the water may slowly escape aroundit, the valve E I, the case A, and the basin D,substantially U guardingagainst any danger from overflow as herein shown and described.

while the valve K is closing. 2. The combination of the ball-valve Q,tube Having thus described my invention, what and rod R S, branch tubeT, and valve U, with I claim as new, and desire to secure by Letters thecase Aand basin D, substantially as herein Patent, is shown anddescribed.
